Where is the impurity in the water after the water purifier is filtered, and the filter core must be replaced?

In the process of selling water purifiers, have you ever met a customer who said, "Do you want to replace the filter element in your water purifier"? "Is there any machine without replacing the filter element"? "Frequent replacement of filter elements, good trouble." It is not known that long-term water purifier without changing the filter can not produce clean water, but will cause secondary pollution of water, more dirty than tap water! It must be explained here that the water purifier without changing the filter element does not exist at present. Using a water purifier that does not change the filter element for a long time will not only make it less effective, but also eventually make us drink unhealthy water, thus endangering our health.

The danger of not changing the filter element is so great. Why do many people install water purifiers but do not change the filter element for a long time? To sum up, there are three main reasons.

Firstly, a large number of people just don‘t know what the water purifier is, buy it according to the wind, and see others buy it and wear it. That‘s what the saying goes.

The second reason is that when buying the water purifier, the merchants did not carry out the necessary core change propaganda, coupled with many people do not understand, do not care, do not care, did not do the relevant homework, and never thought about this problem. They thought that the water purifier they bought did not need to replace the filter element. When you talk to them about changing the filter element of the water purifier, they just look at you in amazement and say, "Ah? Really? I don‘t know. "

Third, it is troublesome. Some people buy a water purifier, assuming that the difference is not big, but the effect may be slightly worse, with two years to lose things, why bother to change the filter?

Buying a water purifier is nothing more than doing addition to your health and subtraction for hazards. If you do not replace the filter element, that is to reverse the two arithmetic. The service life of filter element directly affects the quality of water. Only by changing filter element regularly can the efficiency of filtering impurities be guaranteed and the health of water quality be guaranteed for a long time. In addition, the water filter can be used more regularly for several years, which is much more cost-effective than buying a new water purifier. I believe you will count this account.

In a word, if you want to drink clean water, don‘t forget to replace the filter element of the water purifier regularly, or you‘ll get worse.

How often is it suitable to replace the filter cartridge? Generally, the water purifier on the market is five-stage filter, the first PP cotton recommended replacement cycle is 3 months, the second granular coconut shell activated carbon recommended replacement cycle is 6 months, the third compressed activated carbon recommended replacement cycle is 12 months, the fourth reverse osmosis membrane or ultrafiltration membrane recommended replacement cycle is 24 months, the fifth stage after the replacement of activated carbon The proposed replacement period is 12 months.

Of course, the above replacement cycle is in a general calculation, only for reference, because the water quality varies greatly, and each household water frequency also has a greater difference, filter replacement cycle will also be different. Well, you might ask, how do I know when to change the filter element? Nowadays, many brands of pure water machines have core reminders. Therefore, when buying, it is advisable to choose a water purifier with this function.
